Hello all,
I am in gulf and I bought Nissan Sunny n17,
Its called Nissan Almera also and Engine is HR15DE,

Problem with car is that when car gets hot like driving for half hour then it loose power ... and RPM starts tickling when idle ... I feel gas smell also ... so sometimes I press accelerator rapidly to get more speed. Some people said it is fuel pump and some said injectors and some said ignition coil.

My mind say its ignition coil but I cant check them because they are under manifold.

I connected obd2 bluetooth adaptor to see some data at my android but because lack of knowledge I couldnt get any information ... ECU shows two addresses 7E8 and 7E9 ... 7E8 shows nothing no response but 7E9 shows only these => ECU name Transmission, RPM, Engine Coolant Temperature, volts, Throttle position relative and position B,

So how can I diagnose coils or fuel pump,
or how can I get readings from ecu for misfire.

Thanks,

Get a real OBDII scanner tool if you can't get your bluetooth dongle to work, or maybe just go see your Nissan dealer or even a garage with a scanner?

Coil packs are under the plastic engine cover...which is very easy to remove...but without a code, or a full set of spares, it's not going to do you much without understanding what the issue actually is.

Get your codes read and report back.

My engine is HR16DE which have coils under manifold ... bluetooth is reading 7E9 which gives me name of ECU written as Transmission, also RPM, Engine Coolant Temperature, volts, Throttle position relative and position B, nothing else. But it is not reading anything at all from 7E8.
So how can I read 7E8 or maybe by terminal I can issue some commands,
I will try to go for some garage to let them check codes.
And I can read codes from other engines easily except my sunny.

Today I got new symptom,
I drove too much today like 2 hours & when I stopped at signal ... everything was fine ... just fuel was down like two dots remaining ... at signal green I drove and as I pressed gas more engine went off totaly ... all dashboard lights were on ... first time I saw it going off like this ... I parked the car at side and restarted it ... it started back nicely but RPM was tickling while idle ... anyhow no error light/engine light ... what can be the cause of this?

Sounds like you have some money to spend now... I would seriously seek proper help...tranny oil should never get black, not in a healthy transmission anyways.
